depoly user-storage-jpa keycloak quike start?

Question

recently I am trying to implement a custom user storage provider for keycloak in order to integrate keycloak with external database, therefore I cloned the keycloak quick start and used the user-storage-jpa, first of all I copied the conf/quarkus.propeties file to the conf directory of keycloak distribution with the initial properties like this

quarkus.datasource.user-store.db-kind=h2
quarkus.datasource.user-store.username=sa
quarkus.datasource.user-store.jdbc.url=jdbc:postgres:mem:user-store;DB_CLOSE_DELAY=-1

, then apply "mvn clean install " to generate the jar file , after that copied the jar to provider directory, and start the keycloak using " sh kc.sh start-dev", and here where I gt the following error:

Also you can use '--help' to see the details about the usage of the particular command.

therefore I changed the propertes to use a postgres database with the following prop:

quarkus.datasource.user-store.db-kind=postgres
quarkus.datasource.user-store.username=test
quarkus.datasource.user-store.password=test
quarkus.datasource.user-store.jdbc.url=jdbc:postgres:mem:user-store;DB_CLOSE_DELAY=-1

unfortunately, the same error has raised, any help of what I am missing ... thanks in advance.
